Those are 100% plastic.</p>Customer #218858 on ROB-12090 - Multi-Chassis - 4WD Kit (ATV)Customer #218858urn:uuid:984ef6fa-aa27-3b20-3dbf-561fabdc44822014-07-31T20:14:02-06:00<p>Has anyone run one of these with the adafruit motor shield and Dagu encoders? I just put my ATV together and the wheels are definitely turning at different speeds. It&rsquo;s going to be a trick to get one of these to drive in a straight line.</p>tcmichals on ROB-12090 - Multi-Chassis - 4WD Kit (ATV)tcmichalsurn:uuid:1319e56d-d25e-7d28-9cca-6e9ce119589f2014-06-28T22:18:35-06:00<p>Finally got the kit put together. Used an iMX233-OLinuXino-MICRO, wifi USB dongle, TB6612FNG, and bluetooth dongle. The Wifi is used for uploading and editing files. Bluetooth is used to connect to a wiiremote with a classic game pad.</p>Customer #236971 on ROB-12090 - Multi-Chassis - 4WD Kit (ATV)Customer #236971urn:uuid:8c71b4f1-2986-2d61-565d-b836eb0352992014-04-16T13:58:23-06:00<p>mine came with a 5 battery pack.</p>Customer #236971 on ROB-12090 - Multi-Chassis - 4WD Kit (ATV)Customer #236971urn:uuid:346ea4a1-ed91-a9e6-8f9f-767e821e2ef32014-04-16T13:57:29-06:00<p>got mine in today, the frame is pretty solid aluminum . I don&rsquo;t know about the motors yet. but yeah its somewhat a little high in cost, drop $5 or $10 then it could be a solid buy.</p>
<p>edit: just notice, the basic kit is $10 cheaper, it seems just the wheels are different.</p>RobRight on ROB-12090 - Multi-Chassis - 4WD Kit (ATV)RobRighturn:uuid:929f1e48-b265-5397-3f8e-6f3e027f6f472013-11-14T19:10:58-07:00<p>Is there anyway to get some extra motors? Mine dove off my desk and is now having issue with two of the motors :( Id rather not have to buy a whole new kit for parts!</p>
<p>EDIT: For anyone with a similar problem I found where to get replacement motors.</p>

I don&rsquo;t really see anything that justifies the $45 price tag :/</p>Customer #442770 on ROB-12090 - Multi-Chassis - 4WD Kit (ATV)Customer #442770urn:uuid:617f7899-51ea-d66d-67b2-06dc61ea0e672013-11-10T13:00:56-07:00<p>I agree and I&rsquo;m also going to rely on the spec sheet (it matches the DG02S that is printed on the sticker on the actual motors). However, a funny thing is that the box that this kit arrives in says on the back that the &ldquo;Motors Specifications&rdquo; are 6V-9V supply, 800 mA nominal current, and 2000 mA stall current!! Again, I think I&rsquo;m going to trust the spec sheet and plan for 170 mA max @3V, but I thought I&rsquo;d mention this. Maybe one of the sparkfun folks can ask the manufacturer what is up with the numbers printed on the box?</p>PepperNickel on ROB-12090 - Multi-Chassis - 4WD Kit (ATV)PepperNickelurn:uuid:c9aafa41-cbf2-cdfe-f172-87f7c352aa032013-11-07T12:34:24-07:00<p>Thanks, I think this would work just fine.</p>Customer #370739 on ROB-12090 - Multi-Chassis - 4WD Kit (ATV)Customer #370739urn:uuid:2f31a00d-4459-fbbc-b972-97803a67a5c72013-11-04T10:09:21-07:00<p>I&rsquo;m curious, could I use this platform with Macanum Wheels?

So why do we have a 6 battery pack, (1.5 x 6 = 9V). What voltage are the motors rated for? do we have a Datasheet for them? I&rsquo;m curious to know stall current and stall torque,</p>Citros on ROB-12090 - Multi-Chassis - 4WD Kit (ATV)Citrosurn:uuid:3f695388-54e3-28cf-a78d-eed3a01df8512013-11-01T21:41:04-06:00<p>PWM would be the best answer</p>Erk on ROB-12090 - Multi-Chassis - 4WD Kit (ATV)Erkurn:uuid:fd55f4d0-d6b2-d40a-54c4-ee701c5f5c1b2013-11-01T15:50:37-06:00<p>Lego tread!

Are there encoders? on all four wheels? What&rsquo;s the counts per revolution? Inquiring minds want to know!</p>onyxfish on ROB-12090 - Multi-Chassis - 4WD Kit (ATV)onyxfishurn:uuid:a65464a6-b441-9dfd-217c-ffab1e94a4632013-11-01T09:54:36-06:00<p>Are the gears plastic or metal? Is it possible to get specs for the included motors? Stall current, speed and torque? If they&rsquo;ve got enough power this could be a great shortcut for a project I was about to start on using Pololu parts.</p>
